Hilton HHonors has new offer for American Express cardholders in Germany and the UK that can earn bonus Membership Rewards points for their stays at select Hilton hotels between October 1 and December 31, 2014.

Somewhat weird that only hotels in the UK are valid for the German Amex offer while the UK offer has far wider participation.

Here are the terms and conditions of the UK offer:

Membership Rewards enrolled American Express Cardmembers, who receive an invite for this offer directly from American Express will earn 1 additional Membership Rewards points for virtually every £1 spent on room bookings at Hilton hotels when they book, pay and stay between 1 October 2014 – 31 December 2014 (dates inclusive). Offer valid at the time of booking or at check-out on room rate only (including taxes). Visit Hhonors.com/mr/uk to book now. During the campaign period (1 October 2014 – 31 December 2014) Membership Rewards will be credited to the eligible Cardmembers account within eight weeks from when the promotion period ends. For specific enquiries, please contact your Card issuer using the number on the back of your Card.
